きた。ところが本発明者の調べたところでは、バ
ケツトコンベアーで搬送を行つた場合、被搬送物
にかなりの量の傷みや、砕粒が見られた。 Bucket conveyors are already available, in which a large number of buckets are attached to an endless belt, the belt is passed between upper and lower pulleys, the pulleys are rotated, the belt is circulated, and the buckets are used to scoop up objects to be conveyed and transport them upward. Widely used. Since the structure of this bucket conveyor is so simple, it has been conceptually believed that there is no place where the conveyed objects can be damaged or crushed. However, according to research conducted by the present inventor, a considerable amount of damage and crushed particles were observed in the transported objects when the objects were transported using a bucket conveyor.
本発明はこのような発見に基ずき、この傷みや
砕粒の原因を追求し、且つ、その箇所に改良を加

隙に挾まつて、傷められたり、砕かれたりするの
である。しかし、この点については前記の如く、
従来は全く気付かれず、何等の改善もなされてい
なかつた。 First, it was discovered that the main location that caused damage to the transported objects was the bottom of the bucket conveyor. That is, the objects to be conveyed are caught between the descending bucket and the bottom wall of the machine and are damaged or crushed. This is because, in a bucket conveyor, the gap between the bucket and the bottom wall is usually narrow so that as little as possible of the transported objects remains at the bottom after the conveyance is completed.
In addition, even if the machine is relatively wide, the objects remaining at the bottom of the machine will mix with the fine particles of the objects to be transported over a long period of time, and the material will become like a stone wall piled up. Furthermore, this solidifies under the influence of mold and insect damage, forming a solidified layer on the surface of the bottom wall of the machine, resulting in a narrowing of the gap with the bucket. In this way, in a bucket conveyor, there is a narrow space between the bucket and the bottom wall, and since the bucket makes an arc movement here, the objects to be conveyed can get caught in this gap and be damaged or crushed. . However, regarding this point, as mentioned above,
Until now, this problem had not been noticed at all and no improvements had been made.
次に被搬送物の残留について説明を加える。残

だけでは、効率よく残留を無くすことができな
い。 Next, an explanation will be added about the remaining objects to be transported. Theoretically, to eliminate residue, it is possible to eliminate the gap between the bucket and the bottom wall of the machine, but in reality, if the gap between the bucket and the bottom wall of the machine is too narrow, it may cause shaking when the bucket is moved, or the manufacturing process may be affected. Due to errors etc.
The bucket and the bottom wall of the machine come into contact, and this friction causes wear and tear on the bucket and the bottom wall of the machine, and also causes noise. For this reason, the gap between the bucket and the bottom wall of the machine cannot be made narrower than a certain level, and the objects to be conveyed remain in this gap. In addition, in the case of a consolidated layer, the surface is not completely smooth but has some unevenness, so the objects to be conveyed remain in these depressed areas. Therefore, in the past, it was considered that the generation of residue on the bucket conveyor was unavoidable. In addition, in the past, in order to eliminate residue, a method in which a scraping piece was attached to a bucket or belt has already been proposed as Utility Model Publication No. 9-2573 and Utility Model Publication No. 47-10289. Simply installing the product will not effectively eliminate the residue.

とにある。 The present invention has been made in view of the above points, and its characteristics are that the bottom wall is formed into a substantially arc shape with a radius slightly larger than the turning radius of the bucket, and that the bottom wall lightly contacts the inner surface of the bottom wall. Alternatively, a scraping device that moves in an arc in close proximity is attached to a belt or bucket, and a separation point in the form of an inclined step is provided on a steep slope or a vertical position on the ascending conveyance side of the bottom wall.

垂直状の位置に離反点９を形成する。 Embodiments of the bucket conveyor of the present invention will be described below with reference to the drawings. Reference numeral 1 is an endless belt with both ends screwed together to form an endless belt, and a large number of bucket belts 2 are attached to this belt at appropriate intervals. The belt 1 is passed around the upper and lower pulleys 3, and as the pulleys 3 rotate, the belt 1 moves in a circular direction in the direction of the arrow.
also move. Reference numeral 4 denotes a bottom wall of the conveyor, which is formed into a generally arcuate shape with a diameter slightly larger than the turning radius of the mouth end 5 of the bucket cart 2 that moves turning. Therefore, the mouth end 5 of the bucket moves in an arc while maintaining the gap 6 with the bottom wall 4, and scoops up the object A present on the bottom wall 4, leaving only a small amount. 7 is a scraping device, which is attached to the bucket 2 or the belt 1, and as the bucket or belt moves, the end of it scrapes against the bottom wall 4.
It moves in an arc while touching or close enough to touch the inner surface of the In the embodiment shown in FIG. 1, the scraping device 7 is constructed by attaching an elastic member 8 to the outside of the mouth end of the bucket 2. Therefore, the gap 6 between the bucket 2 and the bottom wall 4 of the machine is filled with the elastic material 6, and the transported object A that is to remain on the bottom wall 4 is pushed by the movement of the elastic material 7. , move along the bottom wall surface, and during this movement, some of the objects enter the bucket 2, while others are pushed up further along the bottom wall 4. A separation point 9 is provided on the bottom wall 4. The separating point 9 is provided at a position where the bottom wall 4 is steeply sloped or vertical, and is specifically constructed by forming a sloped stepped portion as shown in the illustrated example. Therefore, when the conveyed object that has been pushed up by the scraping device 7 reaches this separation point 9, it moves away from the scraping device and moves to the sloping step, where it stays once and then is scraped off. When the device passes, it slides down along the slope of the step and is scattered below the bottom of the aircraft, most of which enters the subsequent bucket 2'. Further, the objects to be transported that have not entered the bucket 2' reach the bottom of the bottom wall, are then pushed up by the scraping device, and the above process is repeated.
Finally, all the objects to be transported will be scooped up by the bucket. Note that if the separation point 9 is provided at a too low position, the conveyed object will not be scattered, so the separation point 9 is formed at a position where the bottom wall is steeply sloped or at a vertical position further upward.
また、バケツト２と底壁４との間隙６の寸法は
次の計算式で定める。 Further, the dimension of the gap 6 between the bucket 2 and the bottom wall 4 is determined by the following formula.
Ｌ＝2D＋α

くバケツト２内に入る。 L=2D+α L; Dimension of gap 6 D; Minimum diameter α of the largest grain of the object to be transported; Dimension of appropriate clearance The theoretical basis of this calculation formula will be explained in the case of rice grains. As shown in Figure 5, rice grains are placed on the bottom wall 4.
Suppose that A 1 and A 2 overlap at the plane with the smallest diameter. At this time, if the dimension L of the gap 6 between the bucket 2 and the bottom wall 4 is larger than 2D, which is the height at which two rice grains overlap, the rice grains will not be affected by the bucket,
Will not cause damage or fracture. On the other hand, if the dimension L is smaller than 2D, the rice grains A 1 and A 2 will be crushed or damaged due to pressure due to the movement of the bucket. It is often thought that if L is larger than D, it will not be pinched, but for example, as shown in Figure 6, one rice grain A1 is lying horizontally on the bottom wall 4 and the other rice grain A1 is lying horizontally on the bottom wall 4. If 2 is lying down using the rice grain A 1 as a pillow, he will be under pressure from the bucket. Also, D is the minimum diameter of the rice grain, but if the rice grain is polymerized on a surface other than the minimum diameter, for example, when the rice grain is standing up, when it is compressed by the bucket, the rice grain will immediately reach its maximum diameter. Because it rotates into a smaller plane, it will not be crushed. Furthermore, even if three or more rice grains are stacked on top of each other, when they are compressed by the bucket, the middle grains will be pushed aside, preventing the rice from breaking. It is often thought that if L is made as small as possible, rice grains will not be pinched, but in this case, when the bucket descends, the rice grains are sandwiched between the rice grains and the bottom wall. However, it still causes broken rice. As mentioned above, the dimension L of the gap 6 is inevitably 2D.
+α is required, and with this size, even if the object is subjected to pressure by the bucket, it can evade the pressure by shifting laterally or rotating. Therefore, this dimension is referred to as the free movement distance in this specification. Note that α can be freely determined, but if it is too long, it will put a burden on the scraping device, so
Set to appropriate dimensions. Further, when the object to be transported has a large coefficient of friction, α is set to be somewhat large. Therefore, the larger the minimum diameter of the object to be transported and the larger the coefficient of friction, the longer L needs to be, and an appropriate gap size is determined by taking these into consideration. FIG. 2 shows another embodiment,
In this embodiment, the separation point 9 is provided on a vertical portion of the machine wall, and the scraping device 7 consists of a scraping piece 11 located slightly forward of the mouth end of the bucket 2 and a supporting arm 12 thereof. This scraping piece 11 is made of an elastic material, and its tip is always in contact with the bottom wall 4. Therefore, the last remaining conveyed object A is scraped up along the bottom wall 4 by the scraping piece 11, reaches the separation point 9, and after once staying there,
When the scraping piece 11 passes, it falls off and enters the bucket 2 that follows.

This scraping piece 11' is made of metal, but since there is a considerable distance between its tip and the position where the bucket belt 2 is attached to the belt 1, an elastic action works, and the scraping piece 11' is made of metal.
The tip of 1' is in slight contact with the bottom wall 4. In this embodiment, the objects to be conveyed that have been scooped up by the scooping piece 11' enter the next bucket (not shown).

Alternatively, they may be attached to every few to ten buckets. In the above embodiment, the tip of the scraping device 7 only lightly contacts the bottom wall 4, and since the scraping device 7 has elasticity, the tip of the scraping device 7 does not pinch the conveyed object. Even if it gets stuck, it will not damage the transported object. Further, the tip of the scraping device 7 does not necessarily have to be connected to the bottom wall 4.
It is not necessary to provide it so that it is in contact with it, but it may be provided so that there is a slight gap.

どの利点を有する。 As described above, in the present invention, the gap 6 is provided between the bucket 2 and the bottom wall 4 to form a free movement distance, so as the bucket 2 moves, the space between the bucket 2 and the bottom wall 4 The conveyed object will not be damaged due to being caught in it. In addition, since the scraping device 7 and separation point 9 are provided, it is possible to reliably transport without generating residue, and the residue does not solidify on the bottom wall and narrow the gap 6. The necessary free movement distance can be maintained at all times. Furthermore, according to the present invention, it is possible to completely transport the objects without damaging them, so it is possible to increase the transport yield, and also to reduce the labor involved in cleaning and improve work efficiency. , and pests will not breed. In addition, the bucket conveyor of the present invention has advantages such as a relatively simple structure, low manufacturing cost, and low noise.
